Near-infrared Spectroscopic Sensing System
Abstract: Dairy farming is a demanding process that involves feeding, milking, livestock management, feed crop production, and manure treatment. Large-scale dairy farmers use herd management, but individual cow management is the best method for monitoring the milk quality and progesterone concentration. Near-infrared (NIR) spectroscopy is a non-destructive approach that has been successful in determining quality and collecting quantitative information on foods and agricultural products such as milk. This talk discusses the development of a novel NIR spectroscopic sensing system for online real-time milk quality (milk fat, protein, lactose, solids not fat, moisture content, milk urea nitrogen, and somatic cell count) and progesterone determination, as well as the measurement accuracy when installed into an automatic milking system.
Presenter Biography： Patricia Iweka is currently a peer reviewer at MDPI and was a postdoctoral research associate at the Field Science Center for Northern Biosphere at Hokkaido University, Japan (2021). She was part of the team that worked on the Development of a Near-infrared Spectroscopic Sensing System for Online Real-time Monitoring of Individual Cow Milk Quality and Ovulation Condition every 20 seconds During Milking. A project which was funded by the National Agriculture and Food Research Organization (NARO), Japan. She is a two-time Japanese Government Scholar and She received her Ph.D. titled “Development of Near-infrared Spectroscopic Sensing System for Online Real-time Monitoring of Milk Quality during Milking” from the Laboratory of Agricultural and Food Process Engineering, Hokkaido University, Japan (2019). She has participated in numerous international conferences and received awards including the prestigious Japan Council for Near-infrared Spectroscopy (JCNIRS) award for her outstanding research contribution to the field of agricultural engineering (2018). She is the first from Hokkaido University to receive the JCNIRS award. Dr. Patricia has co-authored peer-reviewed articles and her research focuses on developing a novel near-infrared spectroscopic sensing system for the online real-time determination of individual cows’ milk quality, health, and ovulation status during milking. She is passionate about teaching and conducting interdisciplinary research that focuses on postharvest technology, food processing, agricultural sustainability, and food security.
